Bounty : sending audio to DLNA/uPNP players

I really want to hear my music, stored on Synology, send to different devices in my home through Homey. I have about 10 dlna players at home, four of which also act as a server... So I want to setup a bounty program (actually multiple)...

1) Plex or Squeezebox on Synology* 50 euro to be able to stream music to my dlna-players with synology-on-plex (I guess I need a plex-pass then?) or* 50 euro to be able to stream music to my dlna-players with Logitech Media Server on Synology (Squeezebox-app)

2) Synology audio station* 50 euro for the one who makes it possible to get the players as devices using the synology-interface* 100 euro extra if we can actually send playlists to the devices so if this actually works...* 100 euro extra if there's a complete app with voice-control to send playlists to specified devices

3) dlna/upnp* 100 euro who gets this done through dlna/upnp so without logging in to synology audiostation* 200 euro extra for an app which can send a playlist/songs or a song to a device * 100 euro extra if there's a complete app with voice-control to send playlists/songs to specified devices

I reserve the right to alter the remaining bounties if one of these is accomplished... Also, the bounties may be altered after media-support is added to Homey with FW1.2.x. Judging @Emile 's latest message there won't be support for synology/dlna from the beginning so we could build it ourselves... So Athom itself may also chime in... And finally, if anyone wants to join in we could raise the bounties...

edit 26-1-2017 : Added Squeezeebox-app for Logitech Mediaserver as this goal is about getting things done, not the way it's done

I would be very much interested in DLNA app as well. I would also happily donate such a project. My needs are a bit more more basic: sending standard DLNA commands to my player (play, stop, pause, volume, source, standby)

Tried this before but didn't see any dlna-devices. Now I did, you have to turn on dlna on settings - advanced - uPnP/DLNA and tweak some settings on http-buffering. Adding devices in Homey worked but the app crashed directly after that... I'll file an issue... First goal almost met

Ok, disabeling and re-enabeling the app works. The devices stay online now... But controlling them doesn't work... Nor on devices, nor in flows...

Edit: flows and devices work too but app crashes a lot... I'll contact the dev...

First goal almost there, with the Github Version of the squeezebox-app I can stream playlists to DLNA-devices. There's still a bug to be solved (volume in flow crashes the app) but looks like the first goal is almost done...

You have to install LMS on synology, turn on dlna on settings - advanced - uPnP/DLNA and tweak some settings on http-buffering.

Actually there are 3 core modules, yesterday evening they launched the real initial app org.upnp on github.And it already worked with my heos speakers but still in development, early fase without any icons etcetera

UPNP is working but not all devices... Controlling volume and pause/play works for most of them but I also have a philips-device which crashes the app... Delivered some devices to Athom for testing but not the priority atm.

I have a Philips MCI900 wifi connected audio center (and it does not work). My MCI900 can communicate with any other DLNA software or mobile app. Only thing I want to do with the DLNA is to set the volume to discrete values.
